Darker side of fair

Leela, aged 60 has had a smooth beautiful skin
all her life. Middling brown, in colour she was one of those lucky
women whom age had not caught up with, her skin and even her arms
showing no trace of her advanced age. A tap on her door one fateful
morning however drastically altered her hitherto unblemished skin.
When she opened the door she found it was a door to door sales
person, who said he was trying to promote a new cream made by a well
known local manufacturer I was familiar with. Would she like to
volunteer participating in some trial experiments where a free
facial was being offered, he asked showing her a list of other
volunteers whose ages ranged from 20 to 60.
